Not to mention any new ideas that may come to mind.No - there was brief discussion a few weeks/month ago and Runey chimed in that he still had years of dev ideas/story to finish. At 2-3 updates a year, I'd prolly guess at least 2 years. Ultimately it's anyone's guess since even Runey has had unexpected life events happen to slow down progress.
We still haven't been introduced to the last room character, if we're going to be. We're only just starting the sexual journey for Autumn. Other main characters have a solid start on their stories, but I'd say we're only just in the thick of things in terms of where those are.
